Merge branch 'ux500-gpio-pins-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/gpio
Linus Walleij <linus.walleij@linaro.org> writes: This is a pull request for the GPIO and pin control stuff accumulated in the ST-Ericsson tree. Here we have: - Improvements and fixes and a custom pin config API from Rabin Vincent - Device Tree bindings from Lee Jones - Some accumulated patches by yours truly. - A MSP platform data init patch from Ola Lilja that is merged here due to dependency on pin config work. It is to be used with work being worked on in parallel in the ALSA SoC subsystem. If you wonder about the custom pin config implementation this is to be used as a transition base as I am rewriting the driver to use pinctrl. Expect a final pull request on top of this one that will move the ux500 over to pinctrl. * 'ux500-gpio-pins-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: ARM: ux500: Add support for MSP I2S-devices drivers/gpio: gpio-nomadik: Add support for irqdomains drivers/gpio: gpio-nomadik: Apply Device Tree bindings ARM: ux500: update pin handling ARM: ux500: implement pin API ARM: ux500: remove a bunch of internal pull-ups plat-nomadik: new sleep mode pincfg macros gpio/nomadik: use ioremap() instead of static mappings gpio/nomadik: support low EMI mode gpio/nomadik: fix spurious interrupts with SKE gpio/nomadik: cache [rf]w?imsc gpio/nomadik: don't set SLPM to 1 for non-wakeup pins Also includes an update to v3.4-rc4.
